TECHNICAL FIELD

The present invention refers to the technical field concerning theconstruction of floating walkable surfaces, for example in the form of afloating screed.

In particular, the invention refers to a floating walkable surface, forexample a screed, constructed in such a manner as to be fullyassemblable/disassemblable, thus allowing also an easy access to theunderlying surface, having heating elements integrated in itself.

BACKGROUND ART

Screed construction has been prior art for a long time.

Concerning construction industry, screed is the constructive horizontalelement which is used to achieve one or more of these purposes:flattening a surface, thus making it perfectly flat; distributing theload of the elements above; receiving the final flooring. The screedthickness is variable depending on the ambient type (for example, insidea building can be comprised between 4 and 8 cm). Its purpose is to makethe underlying concrete substrate flat (loft or flooring), secondly, itis necessary to contain pipes and service cables. If the flooring above(ceramics, stone or wood) is laid by gluing, it is exactly on the screedthat the glue is laid. The screed, accordingly with the prior art, istherefore poured in place and generally consists of three materials usedin appropriate proportions: cement, aggregate (sand and/or gravel, forexample) and water. The dose of elements varies depending on theexternal environment and on the location of it (internal or external,for civil or industrial purpose). Quite often additive or othermaterials are added to the typical ones (common examples arepolystyrene, used to lighten screed, or quartz, used to smooth it ormake it more tough). To strengthen it and make it more collaborating, aniron net can be used, as in the case of concrete lofts.

As described above, it is therefore obvious that, accordingly with theprior art, the constructive technique of creed, or, anyway, of awalkable surface in general, leads de facto to the construction of fixednot disassemblable elements and therefore, once placed, they cannot beremoved except that with a demolition action.

In that sense, if for example a maintenance service is necessary on theaccessories under the screed, the service proves to be not simple at alland, on the contrary, it is invasive and destructive.

With the purpose to solve said technical inconveniences, solutions ofthe modular type exist, that is modules placed side by side each other.

Generally, each module is made by a simple carrying panel placed onsupporting foot, so as to make it floating. In this way, the spacebetween the panel and the carrying level creates the housing ofpotential plant design.

This solution creates a better maintenance access to the underlyingareas but has also some technical inconveniences.

Generally, panels are simply placed side by side each other onsupporting feet but not fixed at all, and, if on one side it simplifiestheir mobility, on the other side it can raise some stability issues.Other locking systems can comprise glue which makes the installationlonger and obviously makes more difficult the mobility of the module formaintenance services.

In addition, such system of modular screeds does not integrate anyheating system which has to be provided apart in the gap of theinstallation and requiring an additional assembly action to be takeninto account before the installation of the screed modules.

For example, it is known the publication number KR200400444 whichcorresponds to the preamble of claim 1.

Such an embodiment discloses a module which is only partially made up byparts detachable one another.

In fact, it is formed by a top panel 210 which is connected indetachable manner to a bottom panel 250 whose shape is like an open boxopen at the top, as it is a container for concrete.

First of all, such a bottom panel 250 is welded to an intermediateclosing panel 230, in such a manner as to form a closed containment box.

Concrete is injected into said bottom panel by means of holes 252 and itsets against the inner structure 259 and 259 of such a bottom panel,thus creating a strong adhesion and creating a single non-detachablepiece formed by the bottom panel and the intermediate panel.

In that manner, the module is very heavy, because of the use ofconcrete, and moreover, the insulating system will be made up only byconcrete, also with structural function.

Therefore, it is not possible to replace concrete with lighter materialswith better thermal-insulating qualities, as it would entail a fullremoval of the whole bottom panel and intermediate panel, which isactually a single element with the concrete poured inside it.

Therefore, this embodiment is not convenient and functional and inaddition, it makes the preparing process of the parts more complex, thusrequiring a step of pouring concrete into the container 250.

DISCLOSURE OF THE INVENTION

It is therefore the aim of the present invention to provide aninnovative module for a walkable surface, for example a floating screed,which solves said technical inconveniences.

In particular, the aim of the present invention is to provide a modulewhich allows an easy accessibility to the underlying surface, thus beingeasily disassemblable but also stable at the same time.

In addition, the aim of the present invention is to provide a modulewhich integrates in itself a heating system, which guarantees a fixingsystem at the same time, both of modules with one other and of variouselements composing each module, being applicable/removable rapidly, insuch a manner as to allow an immediate access to parts of the moduleitself or to allow a rapid removal of a module and a rapidre-positioning of itself as well.

These and other aims are therefore obtained through the present modulefor building a walkable surface, preferably a screed, according to claim1.

Such a module (1) comprises a top panel (10) suitable to form a walkablesurface.

Therefore, the top panel can further be covered with finishing elementsor integrate in itself such finishing elements forming the finalflooring (for example a parquet).

It will have well-known technical features in order to fulfill itsload-carrying function as walkable element.

According to the invention, the module (1) further comprises thefollowing elements:

A bottom panel (20) generally sized to be load-carrying;

A panel of thermally insulating material (30) and a heating device (50)configured for emanating heat, both comprised between the bottom panel(20) and the top panel (10).

The insulating panel (30) is a free-standing modular element of prebuilttype.

In order to keep such elements of the module connected together, that isstacked, connecting means (100) are provided applicable, for example,following the assembly of the module, configured in such a manner as toexert a mechanical action according to an approaching direction of thetop panel (10) to the bottom panel (20).

In this way, the various elements of the module are fixed one anotherand the module is ready for use.

Such connecting means are further configured in such a manner as to bemovable (that is fastening connecting means) in such a manner that, asthey are removed, at least the top panel, the bottom panel and thethermally insulating panel interposed between them are disassemblableeach other.

In this way, all said technical inconveniences are easily solved.

The module integrates in itself a heating element together with athermally insulating element arranged to facilitate the heat irradiationupward. The heating element allow to irradiate heat and such a kind ofconfiguration allows a good heat irradiation towards the walkablesurface, thus simply creating a module assemblable with other modulesfor creating a screed able to emit heat. Therefore, heating systems arenot required to be installed below the above-ground screed as separatedelement.

In this way, the module forming the screed, or the surface in general,can be installed on a potential floating support, also with the smallestheights, as the potential heating system is integrated into the moduleitself and has not to be integrated into the space between the screedand the carrying level. In addition, this solution allows a remarkabletime saving during the assembly, as it does not require first theinstallation of the heating system and then the installation of theoverhead screed.

The used connecting means are of the mechanical type, therefore they donot comprise glues, and, for this reason, they are easily removable.Once removed, they allow an easy removal of the parts of each module, ifthis is considered necessary for the maintenance.

The insulating panel is a prebuilt free-standing element and then it iseasily arranged between the panels with no need of fillings withconcrete. Thanks to the detachability between the parts, all the partsare accessible and replaceable, including the insulating layer 30 whichcan be also replaced with other layers made of different materials incase of need.

In this manner, the impediments of the prior art KR200400444 areovercome.

Advantageously, such a surface of insulating material, for example inform of a panel, is (30) placed above the bottom panel (20) and with theheating device (50) comprised between the top panel (10) and such asurface of insulating material (30).

This solution has the advantage of optimizing the heat irradiationtowards the flooring in use to be stepped on, that is the top surface.

Advantageously, the above-described module is of the floating type, asmeans are provided to raise it to the desired level in respect to thesupporting surface.

Such means are advantageously adjustable in height.

It is therefore possible to apply the system to any height of the endproduct, for example up to 1 meter.

Further advantages are deducible from the other dependent claims.

It is also described here, obviously, a screed or a flooring, thereforea walkable surface, formed by the assembly of two or more modules asdescribed.

DESCRIPTION OF SOME PREFERRED EMBODIMENTS

The present invention concerns a module (1) for the formation of awalkable surface, preferably a screed, the module (1) comprising a toppanel (10) suitable for forming such stepping surface.

According to the invention, said module (1) further comprises thefollowing elements:

A bottom panel (20);

A thermally insulating panel (30) and a heating device (50) configuredfor emanating heat, both comprised between the bottom panel (20) and thetop panel (10), the insulating surface being preferable in form of apanel of insulating material (30) placed above the bottom panel (20) andwith the heating device (50) comprised between the top panel (10) andthe panel of insulating material (30);

and wherein connecting means (100) are comprised and configured in sucha manner as to exert a mechanical action according to an approachingdirection of the top panel (10) to the bottom panel (20) in such amanner as to keep said elements of the module stacked on each other,said connecting means being further configured in such a manner as to beremovable in such a manner that, as they are removed, at least saidbottom and panel (20), top panel (10) and insulating panel (30) areseparable and/or accessible each other.

More in detail, FIG. 1 shows a module suitable for creating a floatingscreed or of a flooring in general, and therefore of a walkable surface,according to the present invention.

In the present invention, the term “screed” means any walkable surface,and therefore also a modular flooring in general and the term “screed”is not to be considered with limiting meaning.

The floating screed, as explained below, does not require the use ofglues for its assembly and therefore it is fully disassemblable and/orre-assemblable. In addition, it is structured in such a manner that thesystem of floating support, that is the system allowing to make theheight variable from the ground of the screed itself, allows the purposeof connecting element, by stacking one another the element of the singlemodule, and at the same time, by fixing a module to an adjacent one forthe assembly of the screed.

Therefore, the use of glue for fixing the module to the adjacent one isonly optional in the case of need to make airtight the lateral edgewhich connects a module and the adjacent one.

Describing more in details the invention, such a floating screed iscomposed by modules (one or more than one). Obviously, in the case ofmore than one module, these can be placed side by side, in such a manneras to cover a predetermined area assembling the screed.

Such modules are for example highlighted in FIGS. 1, 2, 3 and a modulecan be put side by side to another one without requiring the use ofglue. For this reason, the single module, if required, can be removedfor accessing to the underlying surface, for example in order to inspectpredetermined areas.

Each module, in turn, is made of more overlapping elements andobviously, easily disassemblable one another, as, in the preferredembodiment of the invention, the same fixing system that fix a module toits adjacent one are advantageously used also to stack the elements ofthe module at the same time. This entails that each part of the modulecan be easily removed and replaced, for example in the case ofrepairing.

Fixing systems, as explained further, are of the mechanic type and exerta pressure in the axial direction and are thus defined of the axialtype.

Obviously, two independent mechanic systems with axial action, one ofwhich for fixing a module to an adjacent one and one for fixing oneanother the stacked parts assembling the module, could be used.

Nevertheless, as said, the preferred embodiment of the inventionincludes an axial-action system which performs the function of the formof stacking and fixing a module to an adjacent module.

FIG. 1 or FIG. 2 show a module 1 which can be put side by side withother identical modules.

Therefore, the single module includes two external panel systems (10,20), that is a top panel 10 and a bottom panel 20.

The top panel 10 is a carrying panel, for example made of Gres, marbleor similar materials.

The bottom panel is equal to the top one, that is a carrying one.

Therefore, such panels are designed for carrying loads through thechoice of suitable materials and thicknesses.

Therefore, the above panel 10 forms the walkable surface and furtherfinishing elements can be applied on it, such as tiles, parquet, etc.Therefore, the finishing elements can be bought separately depending onpersonal tastes and can be applied with glues and adhesives commonlyused in the technical field, once the whole screed is assembled.

As alternative, the top surface 10 can integrate in itself finishingelements (for example Gres, PVC, parquet, marble, etc.), shapedaccording to the form of the top surface, or it can be the end material(with potential decorative processing).

The other elements are included between these two panels (10, 20),comprising:

A panel 30 of insulating material, in such a manner as to hold heat, forexample polystyrene, Styrofoam or similar ones);

A thermal conductive layer 40 (for example of aluminum);

A pipe 50 forming a heating system for transferring heat.

Going into the descriptive detail of the invention, the insulating panel30 is processed in such a manner as to form a series of corridorsincised on its surface that can intersect one another with right angle.For example, FIG. 5 shows very well such a shape, being removed the toppanel. The figure shows for each panel 30 a series of longitudinalparallel one another corridors 31 and a series of transverse corridors31, intersecting the longitudinal corridors. The same can be seen alsoin FIG. 3.

Corridors are of such a size that they can contain the provided pipesinside them, that is the heating system.

Pipes are necessary for the passage of a warm fluid (for example, liquidlike water as inside conventional heating radiators).

Such pipes are connected to a canal and from the canal to a pump and anormal boiler which heats up the circulating water.

The pipe can be one unique flexible pipe passing along corridorsfollowing a set path.

As alternative, it can be modular itself and made of rectilinearsections 51 linking to curved sections 52 which connect two rectilinearsections placed side by side.

In all cases, as it is explained further, the accessibility of eachsingle module allows the repairing/replacement also of segments ofbroken pipes.

FIG. 5, for clarity purpose, shows four modules placed side by side andwherein the top panel has been removed. In this way, the passage ofpipes provided with circular connecting parts, joining rectilinearsegments each other, can be seen very well.

Panel 30 of insulating material (for example, in the case of Styrofoamor polystyrene) can be advantageously in mould, thus being of rapidmanufacturing and low-cost.

The top layer is made of aluminum, metal in general or other materialswith good thermal-conductive characteristics.

The purpose of layer 40, also shaped to trace the form of panel 30 andto couple to it as per FIG. 2, is to transmit heat upwards, that istowards the walkable panel 20 and to level out the spreading onto thetop panel.

The insulating layer 30 is necessary to avoid heat loss downwards.

In this way, such a coupling of the insulating panel with layer 40forming said corridors, in which pipes are passing, guarantees themaximum heat radiation towards the walkable surface 10, thus minimizingdispersions downwards, that is towards panel 20.

Going further with the structural description of the invention, thefixing of elements of each module is obtained de facto thanks to amechanical clamping system of the axial type 100, for example as shownin FIG. 11.

It is formed by a supporting axis, in which a clamping screw 102 insertsitself (or, similarly, a rivet, a bolt or similar ones).

The supporting axis 101 provides a duct 103 having a supporting base104, for example circular one, in such a manner that such a duct can beplaced firmly on a surface (that is the flooring), thus being emergingupwards from it.

The duct 103 is axially hollow, in such a manner as to hold the propersupport element 105 of the module, that is the surface 106 in contactwith the bottom panel. In fact, such a support component 105 is formedby said surface 106 and an axis 107 configured to insert itself in thecanal formed by duct 103.

It is possible to regulate the extraction amount of the support element105 in respect to the duct 103, as the axis 107 is threaded and insertsitself by screwing in the canal of duct 103.

In a variation of the invention (as shown in FIGS. 14 and 15), generallyfor heights over 10 cm, it is possible to use an adjustment nut screwedon axis 107, which pushes and is at the end stroke on the edge of duct103, thus constraining the selected height.

In both ways, the overall heights of the whole axis 101 is easilyadjustable, depending on needs, by varying the raising heights of themodules from the ground.

In its turn, the axis 107 is axially holed with a hole 109 leading tothe surface 106. In this way, the screw 102 is insertable and screwablein the hole 109 which provides a complementary threading, compacting andclamping the elements that intersects as the latter ones are clampedbetween the enlarged head 102 ‘of the screw and the support surface 106.

Therefore, if a module is, for example, perforated at its center pointwith a through hole, once leaning on the plate 106 in such a manner thatits hole is aligned with the hole 109, it is enough to pass the screw upto intercept the hole 109 and clamp the screw so that this stacks themodule, namely its elements that compose it. In case of maintenance, forexample, inspection of the piping 50, it is sufficient to loosen andremove the screw to detach the top panel, the lamina and the otherelements if necessary.

For a better clamping, as also explained below, it is provided the useof a flat washer 110 that is interposed between the head 102 ‘and thesurface of the top panel 10.

Optionally, it can also be provided a head gasket 108 which leans on thesurface 106 (thus interposed between surface 106 and the bottom panel).It is made of plastic and provided with spacing wings for facilitatingthe alignment of the four edges that are leaning on the same surface andto avoid possible creaking.

It has surprisingly been found that a suitable processing or shape ofthe perimeter of each module means that the axial clamping system caneffectively perform the locking function of a module with an adjacentmodule and, at the same time, fix one another the elements forming themodule itself and described above.

Figures from 7 to 10 show in detail such a solution.

The top panel 10 and the bottom panel 20 of each module have a finishingin correspondence of their four corners that is very well highlighted inFIG. 7.

The finishing consists of a removal of material in correspondence of thefour corners.

In the top panel, that removal forms an angular countersink 111(ninety-degrees angle) in correspondence of the corners. It penetratesinto the thickness of such a panel for such a quantity as to hold thethickness of the washer 110 and therefore of the head of the screw 102′that in this way, through the washer, is flush with the panel.Contextually, the angle is removed so as to generate a flat side 113.The side 113 is preferably orthogonal to the diagonal of the panel.

The formation of the countersink, as shown in FIG. 7, is generallycarried out only in the top panel, while the top and bottom panelcomprise a bevel 113.

The countersink 11 has a dual effect. The washer exerts a pressure onthe surface 112 of the panel, generated by said countersink 111, thuscreating a higher-pressure surface of action, useful also to prevent theseparation of a module from the adjacent one.

Furthermore, the screw is flush with the panel, thus not altering thesurface of the same panel to the application of potential finishingelements.

In this way, as shown in FIG. 9, when four modules (A, B, C, D) are putside by side around their rounded corner, the four finished joiningcorners form a through hole 200 in the top and bottom panel with a headcountersink, indeed as shown in FIG. 9.

As shown in FIG. 10, it is possible to insert the screw 102 with itswasher 110, such a screw is screwed on the support axis 101 placed belowin axis with the hole 200 which is formed by putting panels together. Inthis way, the screw passes through the thickness of the modules (in thesense that slides touching their thickness) and inserts itself into thehole 109. The hole 109 is threaded, so the clamping of the screw againstthe plate 106 stacks a module to another one and simultaneously all thecomponents interposed between the modules.

The use of the washer 110 better distributes the clamping pressure andtherefore creates a better stacking.

The system of axial clamping screw (including the equivalent solutionsrivet, bolts, etc.) are advantageous for their simplicity, as simplyscrewing/unscrewing action allows to fasten the whole system or thedisassembly of the screw and/or the possibility to inspect the module.

A further solution may always comprise an axial mechanical clampingaction system in which the axial force is obtained thanks to a springthat pulls a pivot towards the hole 109. In this way, no thread isnecessary. In this case, for example, the lifting of the pivot againstthe spring action could take place with a suitable magnet.

Obviously, the processing by removal of material must also be providedin the elements included between the top and bottom panel and thereforein the insulating layer and in lamina 40.

If the insulating layer extends with a wider area in respect of a singlepanel (10, 20), obviously, the processing is replaced with a simplethrough hole in the insulating layer.

Having described the essential structural elements of the invention, anassembly example is here described to better understand the invention.

Firstly, support axis 101 are arranged to the ground (as shown forexample in FIG. 5). They are the supports on which the described moduleswill lay.

Possibly, these may also be fixed to the ground, for example throughscrews, bolts or also common glue.

Then it is possible to proceed by adjusting the height of these supportaxes so as to define the required height of the final screed in respectto the ground.

As mentioned, and as well known, an appropriate height allows to createadvantageously a positioning slot for cables and wiring in general andalso the air layer that is formed between the screed and the soil worksas a further good thermal insulator.

At this point, bottom panels 20, which are selected in such a number asto cover the entire predetermined area and as a function of theinstalled axes 101, can be arranged. Obviously, also the support axesare selected in number and positioning such as to cover the selectedarea proceeding in the assembly for micro-areas.

The modules near the perimeter of the wall may be cut out of perimetricshape and size so as to go flush with the wall.

Assuming that a number of support axles 101 has established, the bottompanels are laid down on these, as for example shown in FIG. 5.

FIG. 5, or also FIG. 6, show only by way of non-limiting example, fourbottom panels (therefore, four modules) two by two, placed side by side,in such a way as to form a rectangular or squared-shaped screed. If thearea to be covered is wider, of course, other support axes 101 and othermodules can be placed side by side.

The circular tubular connecting elements are highlighted on the outsideof each module only for descriptive clarity but they must be understoodas incorporated in the module structure.

As shown in the example of FIGS. 4, 5 and 6, each bottom panel lays onfour axes 101 through its corners. In particular, each angle of eachpanel 20 lay on a table 106 in such a way that the hole 109 is slightlydisplaced in respect to the bevel of each module. On the single support101 four corners are laying so that the bevels form the hole of thescrew passage in axis with the hole 109, when the modules are pulledtogether.

In FIG. 5, therefore, it is highlighted for clarity purposes the screw102 that penetrates in this point of intersection of four panels 20(point covered by the insulating layer in FIG. 5).

The insulating layer, as shown in FIG. 5, may for example have an equallength to the double length of the panel and an equal width to that ofthe panel. In such a case, it must be drilled in the screw passagepoint.

Alternatively, it could be of an identical size to that of the panel 20and with the identically processed angle.

At this point, once all the axes 101 and 20 panels are arranged withtheir insulating layer (which could also be a single surface), theproceeding comprises the arrangement of the lamina 40 and then thepipes. Finally, the whole in closed by applying the top panels 10 and byfixing them with the screws as FIGS. 8, 9 and 10.

A single screw thus holds the four modules each other and also stackstogether the component of such modules.

In the case of inspection, it is enough to remove the screw for removingsegments of the module or the entire module.

As said, if it is required to better insulate the modules, the injectionof an adhesive at the junction edge between a module and the flanked onecan be provided, even if this makes disassembly difficult.

In a variation of the invention, although not optimal, the samestructure described above might be provided, wherein, however, theinsulating layer 30 and the sheet 40 are omitted and providing thefixing of pipes 50 of the heating system to the bottom panel.

In this case, there might be a more compact solution, wherein, however,a wider heat loss downwards takes place and with more difficulty inarranging the pipe coil (Styrofoam or polystyrene was in fact processedin order to form the slot inside it).

This heat loss can be partially offset by an adequate lifting heightabove the ground.

As described, this modular walkable surface is preferably of thefloating type.

Therefore, nothing excludes the applicability of the expressed inventiveconcepts also to a modular structure applied in non-floating manner andthus maintaining the advantage to allow in any case the inspection ofthe internal electric heating elements and the replaceability of themodular elements themselves.
